Abstract

See full text

A device controller having an autodisk controller is presented. The autodisk controller in monitor mode is capable of monitoring the address of incoming data blocks and, when a target address is reached, triggers a switch of the device controller to buffer mode. In buffer mode, the autodisk controller is capable of monitoring parameters regarding incoming data blocks and reporting status or errors to a microprocessor. The autodisk controller can, for example, check for Id errors, EDC errors, copyright errors, addressing errors, or data area errors. The autodisk controller can also monitor the memory buffer and determine when it is full. The autodisk controller, therefore, relieves the microprocessor of the duties of monitoring incoming data blocks and error checking those data blocks.
